...Min Chen; Carl R. Knospe A new experimental approach to identify the cutting dynamics in turning operations is presented. This method treats the problem as a closed-loop gray-box identification problem and is based upon spectral analysis and least squares estimation techniques. An active magnetic...

... the effects of base metal and arc length, the arc column was also sampled horizontally as layers for spectral analysis. Results showed that intensity of argon atom lines is determined by arc length and is independent of variation of welding conditions. Based on these findings, a compact arc light sensor has...
